A yellow circle face with black eyes, animated eyebrows, and a smiling arc mouth is drawn in SVG using D3 v5. The example demonstrates basic shapes and transitions, with the eyebrows moving up and down in a looping animation via chained `transition` calls. Code imports `select` and `arc` from D3, uses SVG attributes like `cx`, `r`, and `path` with an `arc` generator, and positions elements relative to the SVG center. Static eye circles and a mouth path complete the composition.
